Pineapple tarts

Went to the bakery supplies store today and saw they have pineapple jam from Thailand. It is the first time I see they sell the pineapple jam from Thailand and since it is only RM7.50 per kg per pack so I bought one pack home to try. I baked some pineapple tarts using the jam since my daughter likes pineapple tarts but the pineapple jam is too sweet to my liking. I have only use half of it and now I am wondering what to do with the rest of the jam.



The recipe for the tarts:
300g superwhite flour
200g margarine
2 egg yolks
1/2 egg yolks
1/2 tbsp pineapple essence
1/2 tsp vanilla essence
500g pineapple jam

I made about 55 tarts out of the above recipe and the cost is about RM8 only.
